Structure of coordination compounds

Structure of coordination compounds Linear for two-coordination, Trigonal planar for three-coordination, Tetrahedral or square planar for four-coordination Trigonal bipyramidal or square pyramidal for five-coordination, Octahedral (orthogonal) or trigonal prismatic for six-coordination, Pentagonal bipyramidal for seven-coordination, Square antiprismatic for eight-coordination, and Tri-capped trigonal prismatic (Triaugmented triangular prism) for nine coordination http://en.wikipedia.org/wiki/Complex_(chemistry)
